Possibly. There was a code that could be put into the MGS HD Collection to unlock all the VR Missions, so I'd imagine the respective codes for the DMC games would still work, too.

An HD collection is just remastering the audio and video, so it they're leaving the original coding of the game intact, along with whatever cheats that could be activated.
